I bought a B/W laser printer and have been generally impressed with the lack of BS that came a long with it.
It did ask for toner once, so I bought something from a third-party.
No direct experience, but I recently read[1] Brother HL-L3220CW counts printed pages, and refuses to print after a set number of pages, even if there's still toner in the cartridge. Some models have a way to reset the page count but this one apparently does not.

(I also use a Brother B/W laser printer, got it second hand for almost nothing, works fine)
The post did mention the other toners that came with the printer also locked, but I think I remember reading elsewhere that those printers are cheaper precisely because they come with EcoPro-only toners in the box.
